For determining the pH-value in saltwater aquaria
The pH value or “degree of acidity” indicates how acidic or basic (alkaline) water is. Pure water is neutral and has a pH value of 7. If the acidic components outweigh the alkaline components, the pH value falls (pH < 7), if the alkaline components outweigh the acidic components, the pH value rises (pH >7). Many organisms are extremely sensitive to significant fluctuations in the pH value.
In saltwater aquariums, the optimum pH value range is between 8.0 and 8.5, as it is in the ocean. Significant fluctuations and overly sharp decreases or increases in the pH value should be avoided at all costs. Therefore, the degree of acidity in the tank should be tested on a regular basis.
The pH-reagent from Tropic Marin, especially developed for freshwater, allows the determination of the pH-value with the help of a finely tuned color scale, which shows a range of 7.4 – 9.4 pH-units.
